Title (EN) LIGHT SOURCE COMPRISING A LIGHT RECYCLING DEVICE AND CORRESPONDING LIGHT RECYCLING DEVICE
(FR) SOURCE DE LUMIÈRE COMPRENANT UN DISPOSITIF DE RECYCLAGE DE LUMIÈRE ET DISPOSITIF DE RECYCLAGE DE LUMIÈRE CORRESPONDANT
Abstract:
(EN) The invention relates to a light source (1) comprising a light-emitting device (3) and a light recycling device (5), said light recycling device (5) is located in an optical path (7) of the light-emitting device (3). The light recycling device (5) comprises at least one light recycling member (9) for changing at least one physical property of light passing it and at least one thermally conductive member (10, 11) capable of conducting heat generated in the light recycling member (9), said thermally conductive member (10, 11) is in thermal contact with the light recycling member (9) and at least one heat sink (12). The invention further relates to a light corresponding recycling device (5).
(FR) L'invention concerne une source de lumière (1) comprenant un dispositif émetteur de lumière (3) et un dispositif de recyclage de lumière (5), ledit dispositif de recyclage de lumière (5) étant disposé dans un chemin optique (7) du dispositif émetteur de lumière (3). Le dispositif de recyclage de lumière (5) comprend au moins un élément de recyclage de lumière (9) servant à modifier au moins une propriété physique de la lumière qui le traverse et au moins un élément conducteur thermique (10, 11) capable de conduire la chaleur générée dans l'élément de recyclage de lumière (9) ledit élément conducteur thermique (10, 11) étant en contact thermique avec l'élément de recyclage de lumière (9) et au moins un dissipateur thermique (12). L'invention concerne en outre un dispositif de recyclage de lumière (5) correspondant.
